The serpentine belt used on 1993 Chevrolet trucks is a single belt, driven by the engine crankshaft pulley, that drives all engine accessories such as the water pump, power steering pump, alternator and air conditioning compressor. Because several of these belt-driven accessories are essential to the operation of the vehicle, a a broken serpentine belt will leave the driver stranded. Therefore, it is a good idea to replace the serpentine belt before it wears out completely and breaks. No specialized tools are necessary to perform the job.
Tools Used: Tools, Socket wrench set with ratchet., New serpentine belt.
Replace Serpentine Belt
Insert a ratchet socket-drive into the square slot on the belt tensioner. Rotate the belt tensioner to release the tension on the belt, then slip the belt off the tensioner pulley. Slip the belt forward off of the remaining pulleys and remove it from the vehicle.
Slip the new belt over each pulley. Be certain the belt is routed correctly by comparing it to the belt-routing diagram that can be found printed on a sticker underneath the hood. Also check that the belt ridges are centered properly within the grooves on each grooved pulley.
